Hi,
I've got an issue with my gamin 5 mainboard regarding uefi/legacy boot order.
System setup:
. M.2 SSD (recognized as pci-e device) with a working windows 7 o.s., bootable from uefi bios.
. Normal hard drive on SATA port 1
. cd/dvd/blu-ray burner on SATA port 3 (from here on calling it the 'dvd drive')
I've tried to boot from a backup program's emergency cd to make a drive image of my ssd's O.S. partition, but the uefi cd/dvd boot option doesn't recognize the disc as being bootable. Setting it to legacy cd/dvd worked fine so that's probably because disc isn't uefi compatible. So, for that reason I've enabled the 'legacy + uefi' mode and added the legacy cd/dvd option to the top of the boot order list. Problem is, the system doesn't want to boot from the SSD anymore.
Here are some things I've tried:
When I set the boot order to: 1) uefi cd/dvd, 2) uefi windows boot manager, and NO disc in the dvd drive, the system boots from the SSD.
This is correct.
When I set the boot order to: 1) uefi cd/dvd, 2) uefi windows boot manager, and a non-uefi disc in the dvd drive, the system also boots from the SSD.
I think this is correct too because legacy cd/dvd is required to boot a legacy disc, right?
When I set the boot order to: 1) legacy cd/dvd, 2) uefi windows boot manager, and there is NO disc in the dvd drive, the system won't boot at all. Saying: "reboot and select proper boot device or insert boot media in selected boot device and press a key".
If I put a non-uefi disc in the dvd drive, the system boots from the dvd. The backup software also recognized all devices, including the SSD.
And if I go to the bios boot menu (F11), I can select the uefi windows boot manager and the system correctly boots into the O.S.
In 'the old days'
, having a boot order like that, the system would skip an empty dvd drive and continue on to the next item in the boot priority list. Somehow, this system does not.
What am I doing wrong here?
I do have an old bios though. v1.2. Although looking at the descriptions of the newer bios versions, I don't see any mention regarding this issue.
